Question

Evaluate a(b - c2) if a = −2, b = −3, and c = −1

Answer 1

6+4= 10

Explanation:

Write the equation.

Now substitute the values for the letters in the equation. ( the negative 1 is multiplied by 2 and it becomes negative 2 )

Now we open the brackets by multiplying the -2 with -3 giving us Positive 6 or just 6. then multiply -2 with -2 which then becomes positive 4 or just 4....

the negatives become positive because of the + plus + = -, and - plus -= +

and then we do 6 plus 4, which equals 10
